grinding efficiency in ball mill grinding

Mechanisms of Grinding

grinding efficiency is rapidly reduced by the buffering effect of the fines as the balls impact on the mill charge. The continuous process comprising a classifier and a mill in series, the classifier returning over-sized product to the mill, is called closed-circuit grinding (see Fig. 4.6(c)).
